Abstract:
In this study, the effect of beverages (Coke TM,
Sprite™, Ribena™, Chrysanthemum tea and
mineral water) on the demineralisation of the enamel
surface was investigated. Demineralisation was
determined by the rate of calcium released from the
enamel surface on exposure to the beverages.
Calcium was determined using the EDTA titration
method. The pH of these beverages was measured
using a pH meter and found to be in the acidic range
(2.43 to 5.79) while mineral water which served as a
control has a pH of 7.00. Ii was found that the rate
of calcium released from Coke™(0.76 J..lg/min)
showed a significant mean difference from Sprite™
(0.38 J..lg/min), Chrysanthemum tea (0.10 J..lg/min)
and mineral water (0.00 J..lg/min)at p< .05, but was
however not significantly different from Ribena™.
Likewise, Chrysanthemum tea and mineral water
also showed statistically no significant mean
difference in the released of calcium during the study
period. The results obtained in this study indicated
that beverages with low pH may pose detrimental
effect on the enamel surface which could have
clinical implication, especially in people with salivary
gland dysfunction or low salivary flow.
